摘　　要：岩矿心的补取作为重要的技术补救措施,在岩心钻探中是不可缺少的,传统的补心方法操作繁杂,特别是当需要在深孔进行多段补心时不易实现,绳索侧壁补心技术可以方便地进行深孔多点补心,易于保证取心数量和取心质量,对减少钻孔报废具有重要作用。Supplementary taken of rock and mineral cores as an important technical remedial measure is indispensable in rock core drilling.Traditional supplementary coring method is operated miscellaneously.It is hard to obtain especially the cores of multiple sections are needed in deep hole.Wire-line sidewall supplementary coring technology can be used conveniently to obtain the cores of several locations,which can easily guarantee the quantity and quality of core.This method has an important role in reducing the disqualification of hole.
